v.ATTAGHMIIEIN'I FOR SHEETING MACHINES.

Application filed August 13, 1923. Serial No. 657,030.

This invention relates to an attachment or device for sheeting machines or roll feeders for ruling machines, its object being to provide an attachment, or device, controlled and operated at intervals by a counting mechanism, to form a loop'or slack in the paper web passing through the sheeting machine at a predetermined time and in front of the cutter, to supply separator or marker sheets slightly longer than the stack or bunch sheets immediately ahead and immediately following, so that when the counted sheets are delivered finally to the layboard, one upon another, the separator or marker sheets project beyond the rear edge of the stack in spaced relation and between the counted bunches so that the operator need only thrust a finger under the marker sheet t raise a counted bunch from the pile, thus assuring speed and accuracy in unloading the lay board.

My improved looping attachment as shown in the drawings is operated and controlled by any sheet counting mechanism,

2 one being shown and described in a patent issued to me February 1, 1921, No. 1,366,938, Counter and stacker for sheet material. The counter may be attached to a part of the sheeting machine where desired. Va-

rious advantages inherent to my invention, both in structure and function, will appear from the hereinafter detailed description when considered with the drawing forming part of this specification, said drawing being a diagrammaticside elevation of parts of a sheeting machine, parts of a sheet counter, and my looping attachment or device in operative position.

In the drawings I show in a general way a sheeting machine at A, in which is mounted a roll of paper 10, from which the web 11, is taken and passed under and partially around a roll 12, thence backward and upward between two feed rolls, one 13, of steel,

and the other, the top one, 14, of rubber, and from thence forwardly between feed rolls l5 and 16 of steel and rubber respectively, and then further on between a platen roller 17, and a cutter roll 18 where it is cut into sheets, and thence between feed rolls 19 and 20, of steel and rubber respectively.

The sheets C are caused to separate about two or three inches after they leave the feed rolls by tapes of the sheeting machine and are passed under the counting machine above referred to and shown at B, diagrammatically. The sheets then may be passed through ruling rolls shown at 21, and from thence to the lay board 22, on which they are stacked in counted bunches 23, separated by the marker sheets 24, which are longer than the bunch sheets and project backwardly beyond the stack as shown at 25.

At 26, in the drawings I show a trip finger, similar in operation to the trip finger 45, in the patent referred to and which normally rests on the passing sheets of paper and drops into the space between them successively to operate the counting mechanism (not shown here) in the usual way, and after a predetermined number of sheets have passed, a one-revolution clutch 27 similar to clutch B, of above mentioned patent, s released to permit a sleeve 28, (same as 28 of patent) and a cam 29, thereon, to make a full revolution on shaft 30, causing the said cam to throw an arm 31 outwardly which rocks a bell crank lever 32, on its pivot shaft, 33, mounted in the frame of the sheeting machine, at the rear end, the shaft 33 carries an arm, similar to the free end of the bell crank lever to support the rear end of the roller 38.

The arm and bell crank lever are pivotally connected as at 34 and 35, to a link 36, which is divided, the parts having threaded engagement with a turn buckle 37, for adjustment. The free end of the bell crank lever carries a roller 38, extending across the machine the full width of the paper web and is held normally slightly above it, but when depressed, immediately before the cutting operation takes place, (as indicated by dotted lines) forms a loop or off-set 39, in the web, the slack for this purpose being drawn back between rolls 15, 16, and 19, 20, just before the cutter operates to sever the web, thus producing longer-than-normal marker sheet, while rolls 13, 14, retain control of the web 11. Arm 31, is pivoted at 40, to the counter frame and has connected thereto a pull spring 41, to hold the arm against the cam 29 at all times.

The shaft 42, of roll 17 has fixed thereto a power pulley 43, and it is from this shaft the sheeting machine rolls and the countingmechanism are driven by chains 44, and suitable gears .(not shown).

For the purpose of this invention it was not thought necessary to illustrate the supporting framework and gear connections, as it will be obvious to those skilled in the art,

that my invention may be attached to the framework of any of the well known sheeting machines and counting mechanisms'now in genaral use 7 It is also thought that the operation and utility of the attachment will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elements thereof are susceptible to such variations and modifications as fall within the scopeof'the appended claims.

' What I claim is: a

1. Means for cutting series of sheets from a traveling web, means forperiodically fornr ing a slack in said web, said slack being fed forward to a cutter to make longer sheets which are delivered on a pile for the purpose of marking counted bunches of sheets, and means for feeding the sheets.

2. Means for cutting series of sheets from a traveling'web and for periodically cutting longer sheets including a roller normally supported above the traveling web and mech anism adapted to depress the roller at predetermined intervals onto the web to produce a slack therein, said slack being fed forward to a cutter to make the longer sheets to be delivered on a pile for the purpose of marking bunches of counted sheets, and means for feeding said sheets.

3. Means for cutting series of sheets from a traveling web, means: for cutting longer sheets at predetermined intervals including a rock shaft, a bell crank on one end thereof and an arm on the opposite end, a roller mounted between the two, and ranging across the width of the web, an arm adjustably linked to the bell crank, in combination with means for operating said last named arm to depress the roller vonto the web to produce slack therein, said slack being'fed forward to a cutter to make the longer sheets to be de livered on a pile for the purpose of marking bunches of counted sheets, and means for feeding the sheets. V

deans for cutting series of sheets from a traveling web, means for cutting longer sheets periodically including a shaft provided with terminal arms, a roller journalled in said arms, means connected to one of said arms for causing the-roller to engage the web to produce slack therein, means'for feeding said slack to a cutter to make the-longer sheets to be delivered on a pile for the purpose of marking bunches of counted sheets, in combination with means for feeding and counting the sheets.
